I just upgraded my laptop to Windows 7 Professional 64-bit. Good times had. I love the new taskbar and the new aero features like shake, peek, and snap. I also like how you can have your background change over periods of time. Right now I have seven different backgrounds that I have set to change every day; one for every day of the week. Above is a screenshot of my current desktop; I'm also running objectdock in addition to the windows taskbar.
